7 Claims.

This invention is directed generally to factory built houses and other buildings and is more particularly concerned with an improved combination door frame and easing construction for use in such buildings.

Primarily, the object of the invention is the provision of a door frame and easing which may be formed from a plurality of parts readily pro duced by factory methods and shipped in separated order to a place selected for a building site where they can then be erected without the use of special tools or requiring the services of skilled labor.

A second object resides in' the provision of a door frame and casing, the parts of which may be produced in large quantities and corresponding parts of two or more units will be interchangeable without the necessity of cutting, shaping or otherwise altering, the parts at the time of assembly.

It is also an object of the invention to provide a door frame having vertically extending side or stud sections formed from wooden strips held in spaced relation by longitudinally spaced blocks, the stud sections being joined at the upper and lower ends by horizontally extending lintel and saddle block bars to form an open rectangular unit, the lintel bar being composed of a plurality of wooden strips joined to form the lintel which is bolted or otherwise secured to the upper ends of the stud sections. I a

A further object resides in providing the rectangular frame unit with a plurality of U-shaped clip members which are secured to the inner surfaces of the side studs and the under side of the lintel bar, door casing sections being held in spaced relation from the frame by the clips, and assembly strips being secured to the clips to retain the casing sections in engagement therewith, the assembly strips and the casing sections having an interlocking relationship whereby the latter are prevented from separating.

Another object rests in forming the opposed surfaces of the strips which form the stud section with registering grooves to receive the resilient ends of spring clips, the latter being provided with laterally directed wing members to engage and support panel means employed as an ornamental finish for the walls. The spring clips may be formed in various manners depending upon the uses to which they are to be placed.

Other objects will be apparent from the following description and the accompanying drawings in which a combination door frame and casing embodying the principles of the present invention has been illustrated in detail. In the drawings:

Fig. 12 and Fig. 13 are perspective views of parts of the wall panel supporting clip structure.

Referring more particularly to the drawings, the entire door frame structure is indicated generally by the numeral I. This structure includes a pair of spaced vertically extending stud sections 2, a horizontally extending lintel bar 3 and a saddleblo'ck bar 4, the latter two bars being disposed between the upper and lower ends of the stud sections and permanently secured thereto to form an open rectangular unit. Each stud section includes a pair of rail members 5 maintained in spaced relation by longitudinally spaced blocks 6, the'rails beingsecured to the blocks to form the stud sections.

The lintel bar is formed from a pair of vertically spaced strips Ba which are joined to form the lintel bar by a plurality of short strips 7 and 8, the strips 1 being slightly longer than the space between the bars and receiving bolts 9 or other securing elements used in attaching the lintel bar to the upper ends of the stud sections. The opposed faces of the bars 6a are formed with registering grooves in which a panel I is disposed. The panel in this instance is formed from plywood and is braced by the strips 8 disposed at each side thereof. At each and and adjacent to the upper portion, the panel [0 has a small section cut out to provide a space for the reception of the ends of the upper bolts 9, the space also permitting access to the bolts in the operation of securing the frame structure in assembled relationship.

The saddle block bar has a rectangular cross section and is secured to the lower ends of the stud sections by screws which extend through the lower portions of the stud sections and into the ends of the saddle block bar. Additional bolts are provided at the lower ends of the stud sections, these bolts cooperating with the screws to hold tenon members II in secure relationship with the lower ends of the stud sections. Similar tenons are provided at the upper ends of the stud sections, the ends of these tenons projecting above and below the frame and being adapted for positioning between spaced rails l2 of joists l3 which form a part of the building framework.

These joists may be of any desired configuration but the door frame and casing forming the subject matter of this invention is designed particularly for use with joist members constructed in accordance with the principles set forth in our copending application Serial No. 329,144, filed April 11, 1940. Suitable bolts or other securing elements may be passed through the rails of the joists and through the ends of the tenons therebetween to secure the door frame in the proper relation to the building framework. Prior to positioning the tenons between the spaced rails of the joists, bearing plates M are positioned in engagement with the ends of the stud sections to prevent contact between the end portions of the stud sections and the joists.

The plates M, as illustrated in Fig. 5, comprise rectangular sheet metal members with a single rectangular hole formed near the center. These plates prevent relative movement between the door frame and the joists and eliminate wear at these points. The upper side of the lintel bar and the lower side of the saddle block bar are provided with tenons l5 for engagement with joists disposed between the joists in registration with the stud sections. The tenons l5 are considerably shorter than the tenons H and, if desired, the securing elements may be eliminated at this location. The bearing plates, however, are employed between the joists and the lintel and saddle bars as it is necessary to prevent contact between the bars and the joists.

At the time of fabrication of the door frame, a plurality of U-shaped clips I6 are secured to the inner faces of the stud sections in longitudinally spaced relation, the under side of the lintel bar also having similar clips secured thereto. These clips are preferably formed of strip metal and are U-shaped, having laterally directed flanges IT at the upper ends of the U-shaped body, the flanges being formed with openings for the reception of screws [8 to attach the clips to the portions of the frame. The lower bar [9 of the U-shaped body is bent at its central portion to form a pair of angularly related sections for engagement by the door casing construction to be set forth hereinafter. At the central portion of the bar l9, an opening is provided and a nut 20 is welded on the inner side of the bar in registration therewith.

After the door frame has been placed in proper position at the time the building is being assembled, a sectional casing 2| is secured thereto. This casing includes side and top rail sections 22 and 23 and saddle strips 24. As illustrated in Figs. '7 and 8, the side and top rails of the casing are formed from bar stock preferably of wooden or composition material. The bar includes inner and outer surfaces 25 and 26, the first of which is formed with a longitudinally extending groove 21 adjacent to one longitudinal edge. The outer surface of the bar is slightly beveled, also adjacent to the same edge. When the rails are positioned in assembled relation with the door frame, the beveled portion of the rear surface is in engagement with the inclined sections at one side of the U-shaped clips. This arrangement places the casing rail at one side of a plane passing longitudinally and transversely through the central portion of the door frame. A second strip is disposed in a similar relation on the opposite side of the center portion of the casing with the bevel portion of the rear surface in engagement with the other angular sections of the U-shaped clips. After the casing sections have been so positioned, the grooves 21 of the sections will be disposed adjacent to the central portion of the frame. To retain the sections in this position, a partition strip 28 is disposed in'overlapping relation with the adjacent edges of the casing rails.

The strip 28 has its rear surface provided with a plurality of longitudinally extending ribs 29 and 30, the latter rib being in the longitudinal center of the rear surface and disposed when the strip is properly positioned between the adjoining edges of the casing sections. The ribs 29 enter the grooves 21 in the casing sections and are held therein by assembly screws 3| which extend through openings formed in the strip 28 and into the nuts 20 on the clips. By threading the screws 31 into the nuts, the strip 28 will be drawn into firm engagement with the casing sections, causing the latter to be clamped firmly against the clips. Due to the angularity of the portions of the clips with which the casing sections engage, these members will tend to move outwardly. The ribs 29, however, will resist this movement and the sections will be firmly retained in proper position. The adjoining ends of the side sections of the casing and the top rail may be cut off at an angle or one might overlap the other, depending upon the desires of the manufacturer.

The saddle strips 24 are similar to the side and top rails but are formed of strip material which is less in thickness. The saddle strips have grooves formed in the upper surface to receive ribs 32 formed on the under surface of a saddle plate 33. The ends of this plate may be extended under the lower ends of the partition strips used to secure the side rails and if it is necessary, screws or other securing devices could be extended through the plates 33 and into the saddle block bar. The casing and frame unit is finished by securing wall panels 34 to the front and rear surfaces of the frame. The edges of these panels terminate in slightly spaced relation from the casing sections and the openings formed by this spacing are closed with molding strips 35. Any desired fastening means may be employed to assemble these molding strips with the casing. The outer side edges of the casing sections have a rearwardly offset portion toform a seat 36'for en gagement by a shoulder 31 formed on the molding strip. This arrangement is provided-to insure the proper positioning of the molding strips at the time of assembly.

In some installations, two doors are disposed in the same wall and are arranged in relatively close relationship, In such instances, one stud may be employed between these doors as disclosed in Fig. 10. In this form of the invention, the stud has U clips secured to the outer sides of each rail and casing sections are secured thereto in the same manner as above described where a single casing is secured to one stud.

In Fig. 11, a slightly modified form of frame is illustrated, wherein the U clips are secured to the side edges of the rails of the stud. In this form, the casing is also secured to the U clips in the same manner.

To assist in the proper positioning of the wall panels, the opposed faces of the rails 5 are provided with longitudinally extending grooves 38. As illustrated in Figs. and 11, these grooves receive the curved outer ends 39 of spring clips 40, the latter being provided with a plate 4| which extends beyond the sides of the stud and is provided with tongue members 42 for engagement by the finishing panels. In other instances, the clips 49 remain plain and receive spring tongues 43 of panel mounting members 44. The members 44 include a body portion which projects from the tongue 43 and is bent to provide angularly related sections 45 and 46. The section 45 extend between the adjoining edges of the wall panels 41 and the section 46 is disposed in a saw slot formed in the edge of one panel. When the finishing panels are being applied, the one having the saw slot is in engagement with the edge of the stud and the tongue 46 is positioned in the saw slot. The clip is then moved longitudinally of the slot to dispose the tongue 43 back of the body of a clip 40. The panel will then be retained in engagement with the stud.

To facilitate the disposition of the tongue 43 in the rear of the clip 40, the free end of the former member is curved as at 48. Clip members having slightly different shape may be employed when horizontal joints are produced between the wall panels, the joint illustrated being a vertical one.

From the foregoing, it will be apparent that a combined door frame and casing construction has been developed which will permit the parts thereof to b manufactured by factory methods and shipped in a knockdown condition to a building site where they may be assembled without alteration by relatively unskilled workmen. The various parts may be dismantled after being once assembled and reassembled without. destroying or requiring any refinishing of parts thereof.
